The NVIDIA GeForce GTX 650 Ti is rumored to launch soon, and so far specifications have leaked on the reference design as well as two custom cards from ASUS and Galaxy. Zotac is the latest manufacturer to have its GTX 650 Ti lineup leaked, and the company is bringing as many as three graphics cards to the GK106-220 Kepler family. In all, Zotac is rumored to be launching one 1GB GTX 650 Ti and two 2GB GPUs – all with vared levels of factory overclocks. Video outputs on all three cards include two DVI and two HDMI connectors.

The Zotac GTX 650 Ti 1GB stays close to the reference design, but bumps up the GPU core clockspeed to 941 MHz. It also includes 1 GB of GDDR5 memory on a 128-bit interface clocked at 1350 MHz (5400 MHz effective), which matches the reference design. The price of this card is said to be $160, and features a custom cooler from Zotac that is similar (but smaller than) to the cooler used on the company's GTX 660 Ti GPU wich we recently reviewed.

The Zotac GTX 650 Ti 2GB is, as the name suggests, a GTX 650 Ti graphics card with 2GB of GDDR5 memory. It features Zotac's custom cooler, and a single PCI-E 6-pin power connector. The GPU clockspeed is 941 MHz and the memory clockspeed is 1350 MHz. The extra 1GB of graphics memory is nice, but it is still on a 128-bit interface so don't expect too much of a performance boost. MSRP of this card is rumored to be $180.

Finally, the GTX 650 Ti 2GB AMP! Edition is Zotac's highest-end GTX 650 Ti graphics card. It comes with the GK106-220 Kepler GPU and 2GB of GDDR5 memory on a 128-bit bus. Powered by a single 6-pin PEG connector, the factory overclocked graphics card is clocked at 1033 MHz for the GPU and 1550 MHz (6200 MHz effective) for the memory.The Zotac GTX 650 Ti AMP! Edition comes with the company's custom cooler and is the first card to feature factory overclocked memory. The rumored price of this card is $190. Unfortunately, that puts it fairly close to the price of a reference GTX 660, which may make this card a hard sell. The factory overclocks are impressive, but saving up the extra $30 needed to get a GTX 660 is likely a better idea because it will still offer up better performance thanks to the additional CUDA cores and wider memory bus.

The following chart compares the three Zotac cards to the leaked reference specifications.

Further, this chart compares the leaked specifications of the top end cards from each manufacturer (at least, the ones we know of so far) to the highest-end Zotac GPU: the 2GB AMP! Edition.

Inno3D is also rumored to have a GTX 650 Ti graphics card coming out, but we don't know clockspeeds or price on it. Only that it has two DVI and one HDMI connector, a single PEG power connector, and a custom cooler.

Overall, the Zotac card measures up well, with pricing being the only major disadvantage. The 2GB of memory, factory overclocks, and two HDMI ports are welcome additions, however. Interestingly, the Zotac card is not the highest clocked graphics card overall, but it is the only one that features overclocked memory. It is unclear to me why manufactuers of NVIDIA cards are so hesitant to push the memory clockspeeds (or if they are even allowed to), but Zotac seems to prove that it is possible to do so.

Also worth pointing out is the rumored pricing, as some of these custom graphics cards are pushing $200 (especially the ASUS card when coverted to USD... I'm sure that has to be in error...), and reference GTX 660 with the full GK106 Kepler core are only $230. It will be interesting to see if these rumored prices turn out to be true, and how well Zotac's factory overclocked 650 Ti models sell.

You can find more photos of the Zotac GTX 650 Ti graphics cards on the Videocardz website, and brush up on the GK106 Kepler GPU architecture in our review of the GTX 660 graphics card.
